K-REACH for Small Importers: What to Handle First, What Can Wait

South Korea runs its own chemical regulation system, separate from the EU's REACH, and it applies if you import or sell chemical substances, mixtures, or certain products containing them into the country. For a small team without a dedicated compliance person, the goal isn't to master every clause of K-REACH on day one. It's to know which requirements are non-negotiable now and which can be worked through over time.

**Start with volume.** K-REACH registration is required for substances imported or manufactured above one tonne per year. If you're bringing in smaller quantities, this threshold may not apply to you yet, but it's worth tracking your annual volumes so you know when you're approaching it. Don't wait until you cross the line to find out what registration involves — by then you may already be out of compliance.

**Get your safety data sheets in order.** Any hazardous substance you import needs an SDS in Korean. This is often the easiest thing to get wrong, because suppliers frequently provide SDS documents in English or another language by default. Ask your supplier directly whether a Korean-language SDS is available before you commit to an order, not after the shipment has left.

**Check for CMR classification.** If any of your substances are classified as carcinogenic, mutagenic, or toxic for reproduction, that classification affects your K-REACH obligations. This is a detail that's easy to miss if you're relying on a generic product description rather than the actual safety data.

**What can wait.** You don't need to become a chemical regulation expert to get started. Focus first on knowing your import volumes, confirming your SDS documentation is in Korean, and flagging any CMR-classified substances. The finer technical details of registration can be worked through once you know whether they apply to you at all.

The simplest way to avoid trouble is to push these questions back to your suppliers early, before goods are on a vessel. Asking for the right documentation upfront is far cheaper than discovering a gap after the shipment has arrived.
